Discusses problem solutions for questions originally posed in the column "Food for Thought from Jay's Diner." (YDS)

Describes the entire process involved when an untried problem was presented to a group of teachers. The lessons learned from their struggles are helpful reminders that open-ended problems should be presented to high school students. (Author/NB)

Examines student solution strategies to a problem that appeared previously in this journal. (YDS)

Focuses on the importance of building from mistakes in mathematics instruction to develop better reasoning and problem-solving abilities. (Contains 11 references.) (YDS)

Presents the Shopping Spree problem to teach students the concept of estimation. (Author/NB)

Focuses on children making sense of multiplication. In an activity called "Silent Multiplication," students use what they know about easier multiplication problems to solve increasingly difficult, related problems mentally. (Author/NB)

Develops computational fluency using a game format. Activities involve a standard deck of playing cards. (Author/NB)

Presents responses to the Average Days of Spring problem that appeared in the March 2002 issue of this journal. (Author/NB)

Describes student work with linear and nonlinear relationships illustrating algebra skills and understanding which are important to introductory algebra. (YDS)

Describes a series of lessons in which 6th grade students explore notions of rates of change and their effect on the shapes of graphs. Addresses aspects of the algebra content standard for the middle grades. (YDS)

Explains big ideas in algebra that help students connect ideas with procedures in different mathematical topics to build a relational understanding of algebra. (Contains 10 references.) (YDS)

Previews this special issue of "Mathematical Thinking and Learning," which describes models and modeling perspective toward mathematics problem solving, learning, and teaching. Discusses its characteristics and foundations and provides an example of a model-eliciting activity. (KHR)

Explores the interrelationship between students' problem-solving ability and their science-process skills in earth science. Statistical analyses indicated that a significantly moderate correlation existed between students' problem-solving ability and their science process skills. Results of a t-test also revealed that there were significant mean…

Investigates the efficacy of promoting 8th grade students' problem-solving ability through history of science teaching. After one year of teaching, with the statistical procedure of the analysis of covariance, finds that the experimental group students outperformed their counterparts in the chemistry conceptual problem-solving ability. Initial…

Includes three responses to David Lemire's article "Math Problem Solving and Mental Discipline." Contends that quality mathematics instruction should result in citizens capable of functioning productively in this highly technological, capitalistic, and democratic society. Proposes that mathematics is very relevant for real-life problem solving.…
